Biomimicry of the flexor digitorum superficialis: Systematic literature review.

Biomimicry consists in imitating nature to solve complex human problems. The hand surgeon usually tries to copy and recreate the structure-to-function and function-to-control relationships of the native tissues after damage. With its exceptional structure and biomechanics, the flexor digitorum superficialis (FDS) has been an important source of inspiration for artificial hand system reconstruction. The present systematic literature review highlights the twenty-two artificial hand system reconstructions derived from the FDS, and presents biomimicry as an alternative approach in clinical research in hand surgery.
